Under what conditions do alkyl azides rearrange to imines? I am having some difficulty finding details on this one. I know that reactions involving
free HN3 are unsavory, but I was unaware of its reaction with alkenes, and was also wondering if it can be radicalized to affect to affect
anti-Markovnikov addition using light or peroxide, similar to how addition with HX is affected.

Here is a recent paper with some in-situ reactions of alkyl azides in the presence of copper catalysts: https://www.thieme.de/statics/bilder/thieme/final/de/bilder/...
Additionally, here's a proposed mechanism from the Hu paper:

Here is a pretty interesting overview of the Schmidt reaction.

What bothers me about this is how weak of an acid HN3 is. How would it easily add to an alkene?
